How does I recreate the popup effects on a9.com?

[smithaa02]

If you go to a9.com, do a search, and hover the mouse button over the 'site info' button a bubble pops up with information about that site. What javascript is required to display a blurb like that with the mouseover event?

If you view the page source on a search, you will find:

<a href="http://amznredirect.alexa.com/amzn/redirect_to_detail?url=http://www.iana.org/root-whois/gf.htm" siteInfo="true"><img alt="Site Info" height="15" width="47" src="http://static.a9.com/-/static/images/en_US/shim.gif" border="0" class="site-info"></a>

Which is the Site Info button. I visited amznredirect.alexa.com/amzn/ and the 'Site Info' is a service provided by Amazon.

Hope this helps. ;)
